To all ilv'tom, it may ooneern lie it known that I. \Ynaaaru d. ilraaam.

a citizen of the United l tatesg residing at.

guished from those machines whieh are automati 'ally actuated by and operate to eoni trol ditlerential fluid pressures supplied thereto.

The objects of the invention, together with means whereby the same may be rarried into eti'eet, will best he understood from the following. description at one form or embodiment thereof illustrated in the acrompauyin d 'awings. it. is to be understood, however. that the eonstrmrtion deseribod and shown has been ehosen .tor illustrative purposes merely. and that the in-- vention may he emhodied in other forms without departing from the spirit and scope thereof.

In said drawings: Figure l is a longitndinal sectional view ot the maehine adjnsted for manual operation. Fig. 2 is a vertieal section or the pump ryiinder and piston. taken at right angles to Fig.1 and showing the piston in a ditierent position. Fig. I is a plan view of the parts shown in Fig. 1. Fig. l is a similar view, partly-in sertion. with the seat. the milk rereptaele. and the pump removed. Figs. 5 and G are elevations at right angles to one another of the millt reeeptaelo and pump connected for power operation. Fig. 7 is an elevation of the operating ram and lever with the eonnertingz rod removed.

1; denotes a tame of suitable eonstir'ue-- tiou provided at one end with supporting ens or uprights l3 and at. the opposite end with depending. arms 14-. between whieh extends an axle 15 on which are mounted wheels lti. The longitudinal frame members are preferably provided each with a plurality of apertures 1? for the reception .jeeting from the frame 12,

ot bolts 15 by which the arms it are socured to tln.= t'rame, this arrangement poraiiltin f the p sition of the arms l.-llongitudinally ot' the frame to be varied at will. The axle 13 is arranged to he reeeived in any pair of a series 1.; in the arms- 1 t whereby the heightv oi the i'rame. 1; when resting upon tho wheels l6 may be adjusted. The trame is provided with a handle it) by which the machine may he moved from plat-e to phn'e upon the wheels 1.6.

Mounted up n the frame 1'2 is a base 521 having a series ol apertures 2:? adapted to rereive a bolt 223 for the attarhment of a seat 2-], said bolt being adapted to be received in any one of said apertures, whereb the position of the seat hmgitudinally of the l'rame may be adjusted.

Supported (:n the frame 12 is a milk reireptaele 2:3. to \Vllltll is attached, as by brarltets J13. a pump cylinder 27 having its upper end in rommunieation with the atmosphere. Within said cylinder is a preferaoly solid piston connected by a piston rod 29 with a eross-heml 30 gnidedon rods Ill. The rods 31 are supported by the b "tickets 2!; and may. if desired. he lm'ther supported at. their upper ends by a ba l or upright 82 secured to the milk reeeptarle Elias shown in Figs. 5 and (.3.

it is one object, of the invention to proride milking merhanism rapablo of use either asa portable, manually operated maehine or as a power driven nun-hint when used in loealities where suitable power is available.

To this end the marhine eomprises connections and operating derirea whit-h will be described.

In Figs. 1 to 4 the parts are shown eonneeted ttrmannal operation. Serured to the rross-l aid 250, preferably in a detaehable manner. as by a removable pin 23? passing through ears or lugs 34 projecting from the rross-head. is a pitman 35 pivoted'at its lower end to an arm 36 fixed on a melt shaft 37 journaled in brat-hots 38 serured to the trained). Fixed to the roelt shaft 37 are other arms 3t) ronnerted by rods 4-0 with treadle levers 41 pivoted on studs 42 proraid levers earryiug (readies -13. The arms 31) are eouneeted by other rods 14 with hand levers 45 piv 'ad on studs it; projecting from brackets t? l apertures 1'. formed' cured to theframe 12. By this mechanism the piston 28 may be reciprocated either by hand or foot power or, preferably, byboth,

wfr king the labor of o crating the machine ve light. Moreover tie mechanism is prefera 1y soarranged that when a foot lever 41 on one side of the machine is moving for wardly the hand lever on the same side, as

T3 formed in'the lower bracket 26.,Meading to the milk receptacle and controlled by a check valve 49 opening toward said receptacle. 50 denotes the teat cups, whch may be of any suitable form or type, but which I "guhave herein illustrated as of the form described and shown in my application for Letters Patent filed Feb. 25, 1911, Serial No. L 610,888. Theseteat cups are arranged in the usual sets of suitable number each, each 9.5:; set being connected by a milk pipe 51, controlledif desired by a suitable cock 52, with thecylinder 27. When not in use the teat cups may be supported by any suitable means, as by hooks 53 projecting from the handle 20 as shown in Figs. 1 and 3, or by hooks 54 projecting from the upright 32 as shown in Figs. 5 and 6. .The milk pipes 51 terminate, in ports 55 in the cylinder 27 which are located above the bottom of said 35.. Cylinder or at points intermediate the limits of movement of the piston 28.

' '.I.he milking operation is as follows;

When the piston 28 starts on its upward stroke from the position shown in Fig. 2, the 40.? check valve 49 will close and a partial vacuum will at once be formed in the milk passage 48'and in the cylinder 27 below the piston. When the piston passes the ports 55 on its upwardmovement this partial vacuum is at once communicated to the teat cups through the pipes 51 causing suction to be applied to the teats. Thereafter as the piston continues to rise the milk will be drawn through the pipes 5 1'and will run into the 501- lower end of the cylinder 27 below theports :More or less air will, at the same time, be, drawn through the teat cupsand pipe 51 into the'cylinder' 27. When the piston de-' scends the suction in the teat cups is re- 55 lieved and may even, by reason of the air v drawn into the cylinder 27 on the upward stroke of the piston, be converted into compression as said piston approaches the ports 55 on its downward stroke. After the pisoOIton passes the, ports '55 on its downward movement these ports are. placed in communication with the atmosphere, and any remaining suction or compression in the teat cups completely relieved. Thereafter as the .65 piston continues to descend the milkinthe lower end of the cylinder will be forced into the milk receptacle.

It will be seen that from the beginning of the upward stroke of the piston a partial vacuum is formed in the lower end of the cylinder, without the necessity of exhausting any considerable dead air space, and that this partial vacuum is at once communicated to the teat cups when the piston passes the ports 55.

It will also be noticed that the pipes 511 are in permanent, commumcatlon with the interior of the cylinder 27, there being no check valves orcther devices acting normally to control this communication, it being understood that the cocks 52 are mere hand operated devices to isolate any set of teat cups which may be out of use. After the completion of a suction period caused by the upward movement of the piston, the subsequent downward movement of the piston causes the suction in the teat cups to be relieved. each cycle of operations of .the machine, namely, during the time whenthe piston is below theports 55, the teat cups. are completely vented to the atmosphere, the piston 28 itself serving as a valve for the ports 55 to control this operation. By these provisions all possibility of an accumulation of suction in the teat cups isprevented. A serious objection to machines of this general type as heretofore proposed hasbeen that continuous suction was applied to the teats. As will. be seen this objection is elfectually overcome by the present invention.

In Figs. 5 to 7 are shown, in operative position, the connections whereby the ma chine may be "operated by power. 56 denotes a power shaft journaled in bearings carried bybrackets 57 suitably supported, as by the wall of a barn or other building. 58 denotes a cam mounted on the shaft 56 and cotiperating with a roller '59 carried bya lever 60 pivoted at 61 to one of the brackets 57. The cam 58 is preferably of. substantially the form shown in order togive to the piston 28 a relatively slow upward movement and .a relatively quick downward movement in order to providea relativelylong suction period and a. relatively quick relief of the suction. Where a plurality of cams 58 are employed in order to operate a number of machines simultane- Moreover, for a. certain period in ously these cams are preferablyarranged with their highpoints in difl'ere'nt angular positions on thcbhaft 56 in order to'distribute the load on said shaft. 62 denotes 'a preferably substantially spherical knob atof flexible socketed arms carried by a connecting rod 65 pivoted at 66 to the lever 60. 67 denotes a collar fast on the connecting rod 65 and 68 a collar slidably mounted on the arms 54: and between which collars is interposed a spring 69. Normally the collar 68 holds the arms 64 in engagement with the knob 62. To disconnect the piston rod 29 from the connecting rod the collar 68 is raised against the tension of the spring 69 and the arms 64E separated to release the knob 62. 7O denotes a weight carried by the connecting rod to cause the:

downward movement of the piston 28 when permitted by the cam 58. A weight is prererable for this purpose to a spirhig for the reason that the maximum power is required at the time when the piston approaches the lower limit of its stroke, at which time a spring would exert its minimum force. The force of weight, however, will be substantially constant, or if anything greater as the lower limit of its movement is approached due to its momentum,

The machine is converted from manual to power operation aS follows: The pin 33 is first removed to disconnect the pitman 35 from the cross-head 30 and the knob (32 is screwed upon the upper end of the piston rod 29. In this connection it is to he noted that the knob (32 may, if desired, be left permanently in place upon the piston rod 29, or even formed integral therewith, as it in no way interferes with the manual operation of the machine and is detachably connected with the connecting rod 65. The collar 68 is then raised, the arms 64: slipped into place over the knob (32, and the collar again released. If necessary in order to bring the parts into proper vertical adjustment, the position of th axle 15 on the arms 14 may be raised or lowered, which will position the machine vertically with respect to the shaft 56 and lever 60. In or der to stcadythe machine it may be desirable to rest the wheels 16 against the wall by which the brackets 57 are supported, and if any horizontal adjustment is necessary in] order to bring the piston rod 29 into proper alinement with the connecting rod 65, such adjustment may be effected by varying the position of the arms lei on the longitudinal members of the frame 12.

The milk receptacle 25 is preferably dc tachably connected to the frame 12, as by bolts on screws 71 (Fig, 3) entering openings 72 (Fig. 4) 1n the longitudinal frame members. If desired, therefore, when the power operating mechanism shown in Figs. 5 and 6 is used, this receptacle, together with the pump, may be removed from the frame 12 and placed upon the floor or any other suitable support.
